The length of a rectangle is twice it’s width .if the perimeter of the rectangle is 30 m , find its length and width

Length: 10 m

Width: 5 m

Step-by-step explanation:

First, you should know that perimeter is equal to all of its sides added together. The first thing I did was split the number 30 into two parts, 20 + 10. 20 would be the total length and 20 would be the total width. Divide both numbers by 2 to get the length and width of one side. 20/2 = 10, so 10 m is the length of one side. 10/2 = 5, so 5 m is the width of one side. 5 x 2 =10, so the length of the rectangle is twice it's width. So, the length is 10 m and the width is 5 m. Hope this helped!

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
